Bumpy liquid films could simplify fabrication of microlenses
Have you ever noticed that when heated a film of oil in a pan doesn't remain completely flat? Instead, it forms a wavy pattern that resembles the exterior of an orange. These sorts of deformations inspired a group of researchers to explore whether they could be used to improve and streamline microfabrication processes.
